DOCUMENT:Q233249 20-MAY-2002 [winnt] TITLE :NET SEND May Not Work with Disabled Network Adapter PRODUCT :Microsoft Windows NT PROD/VER:winnt:4.0 SP4 OPER/SYS: KEYWORDS:kbWinNT4sp6fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0, Terminal Server Edition - Microsoft Windows NT Workstation version 4.0 SP4 - Microsoft Windows NT Server version 4.0 SP4 ------------------------------------------------------------------------------- SYMPTOMS ======== When you have a computer with two network interface cards in it, and you use a hardware profile to boot the computer with one of the interfaces disabled, you may not be able to run a "NET SEND" (without the quotation marks) command to the local computername. CAUSE ===== This problem occurs because the Netbt.sys driver maintains an internal name table, visible using the "nbtstat -n" (without the quotation marks) command. When you run a "NET SEND" (without the quotation marks) command to the local computername, Service Pack 4's Netbt.sys file used the first name/address mapping in the local name table, without validating it to make sure it was a legitimate address. RESOLUTION ========== NetBT has been fixed to check for a valid (non-zero) IP address when looking up an IP address in the local name table. To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to: - http://www.microsoft.com/windows/servicepacks/ -or- - Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack For information on obtaining the individual software update, contact Microsoft Product Support Services.
